Purpose:
Prehabilitation (PH) is purported to improve patients’ preoperative functional status. This systematic review and meta-analysis sought to compare short-term postoperative outcomes between patients who underwent a protocolized PH program and the existing standard of care among colorectal cancer patients awaiting surgery.
Methods:
A search in MEDLINE/PubMed, the Cochrane Library, Embase, Scopus, and CINAHL was conducted to identify relevant articles. Repetitive and exhaustive combinations of MeSH search terms (“prehabilitation,” “colorectal cancer,” “colon cancer,” and “rectal cancer”) were used to identify randomized and nonrandomized studies comparing PH versus standard of care for colorectal cancer patients awaiting surgery. The primary outcomes included postoperative morbidity, length of hospital stay, and readmission rates.
Results:
Seven studies including 1,042 colorectal cancer patients (PH, 382) were included. No significant differences were found in intraoperative outcomes. The postoperative complication rates were comparable between groups (Clavien-Dindo grades I and II: risk ratio, 0.82; 95% confidence interval, 0.62–1.07; P=0.15; Clavien-Dindo grades ≥III: risk ratio, 1.02; 95% confidence interval, 0.72–1.44; P=0.92). There were also no significant differences in length of hospital stay (P=0.21) or the risk of 30-day readmission (P=0.68).
Conclusion
Although PH does not appear to improve short-term postoperative outcomes following colorectal cancer surgery, the quality of evidence is impaired by the limited trials and heterogeneity. Thus, further large-scale trials are warranted to draw definitive conclusions and establish the long-term effects of PH.

Objective:
This study was performed to evaluate the efficacy and safety of lurasidone (160 mg/day) compared to quetiapine XR (QXR; 600 mg/day) in the treatment of acutely psychotic patients with schizophrenia.
Methods:
Patients were randomly assigned to 6 weeks of double-blind treatment with lurasidone 160 mg/day (n=105) or QXR 600 mg/day (n=105). Primary efficacy measure was the change from baseline to week 6 in Positive and Negative Syndrome Scale (PANSS) total score and Clinical Global Impressions severity (CGI-S) score. Adverse events, body measurements, and laboratory parameters were assessed.
Results:
Lurasidone demonstrated non-inferiority to QXR on the PANSS total score. Adjusted mean±standard error change at week 6 on the PANSS total score was -26.42±2.02 and -27.33±2.01 in the lurasidone and QXR group, respectively. The mean difference score was -0.91 (95% confidence interval -6.35–4.53). The lurasidone group showed a greater reduction in PANSS total and negative subscale on week 1 and a greater reduction in end-point CGI-S score compared to the QXR group. Body weight, body mass index, and waist circumference in the lurasidone group were reduced, with significantly lower mean change compared to QXR. Endpoint changes in glucose, cholesterol, triglycerides, and low-density lipoprotein levels were also significantly lower. The most common adverse drug reactions with lurasidone were akathisia and nausea.
Conclusion
Lurasidone 160 mg/day was found to be non-inferior to QXR 600 mg/day in the treatment of schizophrenia with comparable efficacy and tolerability. Adverse effects of lurasidone were generally tolerable, and beneficial effects on metabolic parameters can be expected.

A 37-year-old woman was referred to our institution for further management of a mass lesion located in the thoracic cavity. The mass had grown by more than 10 cm over the course of a year and was initially considered to be a scar from previous pulmonary tuberculosis at another hospital. The patient had complained of left-sided flank pain for a year and experienced dyspnea for one month. Chest radiography and chest computed tomography revealed an irregular-shaped mass in the left mid to lower pleural cavity. The mass was widely excised through left thoracotomy. Pathologic examination of the biopsy specimen revealed a malignant spindle cell tumor, which consisted of components of osteosarcoma, pleomorphic sarcoma, and leiomyosarcoma. The patient underwent adjuvant chemotherapy and has been doing well without any evidence of recurrence for 14 months.

The use of mesenchymal stem cells (MSCs) has emerged as a potential new treatment for myocardial infarction. However, the poor viability of MSCs after transplantation critically limits the efficacy of this new strategy. The expression of microRNA-210 (miR-210) is induced by hypoxia and is important for cell survival under hypoxic conditions. Hypoxia increases the levels of hypoxia inducible factor-1 (HIF-1) protein and miR-210 in human MSCs (hMSCs). miR-210 positively regulates HIF-1alpha activity. Furthermore, miR-210 expression is also induced by hypoxia through the regulation of HIF-1alpha. To investigate the effect of miR-210 on hMSC survival under hypoxic conditions, survival rates along with signaling related to cell survival were evaluated in hMSCs over-expressing miR-210 or ones that lacked HIF-1alpha expression. Elevated miR-210 expression increased survival rates along with Akt and ERK activity in hMSCs with hypoxia. These data demonstrated that a positive feedback loop involving miR-210 and HIF-1alpha was important for MSC survival under hypoxic conditions.

BACKGROUND/AIMS: This study examined the effects of hepatitis B virus (HBV) infection state and immunologic capability in both the recipients and donors of allogenic hematopoietic stem-cell transplantation (allo-HSCT) on changes in HBV serologic markers in recipients. METHODS: A total of 537 patients underwent allo-HSCT for the treatment of leukemia, malignant lymphoma, and solid tumor. HBV serologic markers were examined in both recipients and donors prior to and following the transplantation. The mean follow-up period was 36.6 months (range 3-80 months). RESULTS: Of the 537 patients who underwent allo-HSCT, 45 recipients were positive for HBsAg prior to transplantation. Of these 45 patients, 21 were transplanted from anti-HBs-positive donors and the remaining 24 were transplanted from anti-HBs-negative donors. In the former cases, seroconversion was noted in 4 of the 21 patients (19%). In the latter cases, however, no seroconversion was noted following the transplantation. Thirty patients who were negative for both HBsAg and anti-HBs were transplanted from anti-HBs-positive donors, and 15 out of 30 patients (50%) acquired anti-HBs. Four hundred and seven patients who were positive for anti-HBs were transplanted from anti-HBs-positive or HbsAg-negative donors; 8 of these proved HBsAg-positive following the transplantation. There were no changes in HBV serological markers following transplantation in 41 patients who were transplanted from HbsAg-positive donors. CONCLUSIONS: Due to the adoptive immunity that was transferred from anti-HBs-positive donors, a seroconversion of HBsAg could occur in some HBsAg-positive recipients. HBsAg-positive donors had a lesser effect on the HBV serologic markers of recipients. However, a reactivation of HBV can occur following hematopoietic stem-cell transplantation in the cases of recipients or donors with a history of HBV, infection by an accompanying immune suppression. Therefore, prevention should be instigated.

During off-pump coronary artery bypass graft surgery (OPCAB), vigorous displacement and compression of the heart producing significant hemodynamic change are essential for optimal exposure of graft anastomoses. Intraoperative transesophageal echocardiography (TEE) is useful in determining hemodynamic compromise and prompting medical and mechanical support. However, in addition to the loss of contact between the heart and diaphragm during the displacement, swabs or snears underneath the heart interrupt the TEE signal transmission, resulting in a compromised transgastric (TG) TEE view. Therefore, TEE monitoring during OPCAB is usually limited to the mid-esophageal view. The authors placed a saline bag (a surgical glove filled with saline) underneath the heart to facilitate this anterior displacement of the heart, as well as avoid the signal interruption of the TG echocardiographic window. As a result, the optimal heart position with the minimal changes in LV regional wall motion, LV function and mitral regurgitation were found using the TG and other TEE views. The series of velocity-time integral of aortic valvular flow (VTI-Ao) in TG long axis view, in addition to SvO2, were then monitored as a surrogate marker of the cardiac output during a graft construction of the left circumflex artery. It was concluded that the use of a saline bag may be useful in avoiding compromise of the TG TEE view and determine the hemodynamic change using VTI-Ao during cardiac displacement for OPCAB.

OBJECTIVE: The purpose of this study is to evaluate the efficacy and safety of mirtazapine treatment in multicenter population consisting of Korean patients suffering from moderate-to-severe depression. METHODS: Total 163 of in and outpatients with a diagnosis of major depressive disorder (DSM-IV) and 18 or over scores of 17-items Hamilton Rating Scale for Depression (HAMD) received treatment with mirtazapine (15-45 mg/day) for 6 weeks. Efficacy was assessed by HAMD, Montgomery and Asberg Depression Rating Scale (MADRS), Beck's Depression Inventory (BDI), and Clinical Global Impression (CGI) scales and statistical analyses were performed on the intent-to-treat sample (143 patients) using the last-observation-carried-forward method. In addition, reported adverse events, routine laboratory parameters, and vital signs were investigated to evaluate the safety of mirtazapine. RESULTS: Mean daily dose of mirtazapine was 28.4 mg. At the end of the study, the response rate (50% or more reduction from baseline in HAMD scores) was 75.5% and the remission rate (7 or less in HAMD score) was 42.7%. Mirtazapine treatment induced significant reduction in depressive symptoms at the 4(th) day and substantial reduction along the treatment period, as assessed by changes in HAMD, MADRS, BDI, and CGI scales. At the 4(th) day and first week of mirtazapine treatment, the mean HAMD-17 total score was significantly reduced compared that of the baseline and the response rates were 11.9% and 28.7%, respectively. Mirtazapine was well tolerated in general, and somnolence and sedation were the most common adverse events reported. In addition, there were no clinically relevant changes in laboratory parameters and vital signs, although body weight was increased. CONCLUSION: Although this trial had many limitations of open non-comparative study, mirtazapine was demonstrated to an effective treatment for moderate to severe major depressive disorder and was well tolerated. A potentially rapid onset of overall therapeutic efficacy of mirtazapine was suggested by significant changes in all major variables of efficacy after 4(th) day of treatment.

The determination of arterial pressure wave-derived cardiac output (APCO) and central venous O2 saturation (ScvO2) has been introduced as a less invasive procedure for monitoring cardiac function and oxygen delivery. We have used an APCO sensor (FloTracTM) and a monitor for ScvO2 (Vigileo(TM)) in two cases of cardiac valve surgery, where placement of pulmonary artery catheter (PAC) was not applicable due to unfavorable cardiac structure (case 1) and was contraindicated due to an unstable cardiac conduction disorder and arrhythmia (case 2). In case 1, monitoring of APCO was started from the beginning of anesthesia induction and a ScvO2 monitoring central venous catheter was inserted just after anesthesia induction. APCO, ScvO2 and other hemodyanamic information such as arterial BP, CVP, and data obtained from transesophageal echocardiography (TEE) during the pre- cardiopulmonary bypass (CPB) period were measured. APCO and ScvO2 during the post-CPB period showed a reliable correspondence with continuous cardiac output (CCO) and mixed venous O2 saturation (SvO2) as measured by PAC at the end of CPB. In case 2, APCO and ScvO2 were monitored instead of CCO and SvO2. The values of APCO showed a good correlation to intraoperative COs indirectly calculated by the velocity-time integral of the aortic outflow determined in the TEE examination. We experienced that monitoring APCO and ScvO2 is useful for anesthesia management in cardiac valve surgery and can be an alternative to CCO and SvO2 if the placement of PAC and the thermodilution method are not applicable.
